Voyage traces stirred-up Arctic heat
Oceanographers have gathered fresh evidence that turbulence in the Arctic Ocean, driven by the wind, is stirring up heat from the depths.

The research team has measured heat rising from below that matches what is arriving from the autumn sun.

Although their findings are preliminary, the "ArcticMix" team has been taken aback by what they've seen in the raw data.
